年輕成人學生藥物濫用再逮捕相關警示因素：一個來自台灣的全人口世代研究

Factors associated with future illicit drug recidivating for young adult students who misuse drugs: a population-based cohort study from Taiwan

目標：藥物濫用者之再犯率高，但少有研究使用犯罪紀錄探討再犯相關警示因素，本研究目的在探討年輕成人學生藥物濫用再逮捕的相關警示因素。方法：本研究為全人口世代研究。研究起始日為第一次通報藥物濫用的日期。研究對象為102年教育部通報藥物濫用個案（年齡18-24歲），以研究起始日後之一、二級毒品或三、四級毒品為再逮捕指標，探討與個人、家庭背景因素之相關性。採用Cox迴歸分析，計算各因素的「危險比」，追蹤個案從研究起始日至被警方逮捕、死亡、移民或2015年6月30日。結果：共860位藥物濫用學生中有61（7.09％） 位在研究起始日後有一、二級毒品移送紀錄；214（24.88％）位有三、四級毒品裁罰紀錄。一、二級毒品移送高風險族群：非父母監護人、成案前有一、二級毒品刑案移送紀錄等背景因素。三、四級毒品裁罰紀錄高風險族群：監護人非母親、中輟、學習意願低落、成案前曾有三、四級裁罰紀錄等。結論：年輕成人藥物濫用學生再逮捕相關警示因素：曾有毒品犯案紀錄、非父母監護人、中輟與學習意願低落。 Objectives: Although data have discovered risk factors of illicit drug use, there was still rare study discussing this issue based on the following criminal record. The aim of this study was to investigate the factors associated with the following illicit drug criminal record in young adult drug misuse student. Methods: This was a population-based cohort study.

Cox regression model used to assess the association between factors and illicit drug criminal record by hazard-ratio. Subjects were follow-up until relapse of drug misuse, death, migration or June 30, 2015. Results: Of the 860 illicit drug use students, 61 (7.09%) with the following drug criminal record of schedule I and II drugs.
